Abstract
A damping valve for a vibration damper including a cylinder filled with damping medium. A piston rod with a piston is realized in the cylinder so that the piston rod can move axially and the piston can divide the cylinder into two working chambers. The damping valve is located inside a housing and is realized so that it can be adjusted by a solenoid in connection with an armature, which armature is guided in an insulator. A receptacle functions as part of the housing, which receptacle, by an insulator, separates the hydraulic part of the damping valve from the electrical part. A tube socket together with the housing holds the adjustable damping valve. As the insulator, at least one gasket or seal is used, which provides hydraulic and magnetic insulation between a cover of the housing and the receptacle.
